When You Can't Empathize, Care

From Aish.com, Rabbi Pliskin's Daily Lift:

When you empathize with someone, keep in mind that you can never know exactly how they are feeling. You can only make assumptions based on your knowledge of human nature in general, and this unique individual in particular. At times, the best thing to say might be, "I can't know exactly how you are feeling. But I see how strongly this affects you."

It's really hard when you don't really know what someone else is going through, and you want to show how much you care. When you don't know what to say, but inside you are screaming with the pain you know they are going through.
